Question

I’m using RSpec and I want to get result (passed or not), class name, test name (or description) and error message (if present) of each test after once it finished.

So here is a pretty simple code

  describe MyClass do

    after :each do
      #how do I know a test passed, its name, class name and error message?
    end

    it "should be true" do 
        5.should be 5
    end

    it "should be false" do 
        5.should be 6
    end

   end

Your suggestions?

Answer 1

There are a few formatters for test output that can show you which tests passed/failed/pending, and it sounds like you are interested in the one called documentation.

In order to make this formatter available for all your rspec files, create a file called .rspec with content:

--color  # I just like this one for more easily read output
--formatter documentation

This means that when you run a test suite like you have above you will see:

MyClass
  should be true
  should be false (Failed - 1)

  # Individual output for each error would show up down here
